  • Title: Comparative speaking, shouting and singing voice range profile measurement: physiological and pathological aspects.
    Author: Hacki T.
    Journal: Logoped Phoniatr Vocol; 1996; 21(3-4):123-9. PubMed ID: 21275582.
    Abstract:
    The Voice Range Profile (VRP) measurement offers a method for the investigation of voice modalities i.e. speaking voice, shouting voice and singing voice in their mutual pitch and intensity relations. The parameters FO and SPL are evaluated by means of automatic pitch and SPL measurements from (1) sustained phonation /a:/ in the speaker's natural pitch and intensity range, (2) the continuous speaking voice beginning with Pianissimo up to Fortissimo, (3) the shouting voice. Vocal intensity is plotted vertically, vocal pitch horizontally. The displays of the vocal intensity versus fundamental frequency are defined as singing voice range profile (VRP), speaking VRP and shouting VRP. The VRPs are superimposed on the same plot. Their form, their shape and their position to each other are analysed. The physiological relationships between the VRPs of the different voice modalities to each other are defined. The pathological relationships between the VRPs (i.e. reduction, shifting) give information about etiology and pathomechanism of voice disorders.
